What is a Manhole Survey & 3D Chamber Profiling?
A manhole survey provides a detailed visual and structural assessment of underground chambers and drainage systems.
Using advanced 3D chamber profiling, we collect accurate measurements of depth, pipe alignment, flow direction, and internal construction.
We then can produce high-resolution 2D and 3D chamber models that meet CS 551 compliance standards.
These reports are essential for drainage engineers, designers, and maintenance teams needing precise information for repairs, upgrades, or smart motorway infrastructure planning.
Cleverscan Technology: How It Works
Our Chamber & Manhole Inspections
Cleverscan is a specialist manhole survey system designed for high-resolution, non-entry inspections.
Our Cleverscan units are fitted with five cameras and a powerful laser scanner, capturing every detail inside the chamber, including defects, infiltration points, and unmapped features.
Our advanced CleverScan systems perform rapid, high-resolution manhole inspections and chamber profiling reports. A flat scan is created, capturing at high detail every inch of a manhole wall, alongside a dense data point cloud. These are then easily integrated with CAD software or 3D applications.
This allows your engineers and designers to make informed decisions quickly, without the delays of traditional confined space entry surveys.
Why We Use Cleverscan
- Safety: reduces requirement for confined space entry
- Speed: data is automatically uploaded into WinCan
- Accuracy: dense point cloud picks up all the information needed


Importance of Profiling Manholes & Drainage Systems
Profiling is crucial for the effective management of drainage systems, giving valuable insight into the condition of manhole chambers, identifying potential issues before they become major problems.
